Abstract

A method to confirm FEA strain level predictions was developed for small nitinol-compressive specimens by taking micron magnitude measurements from SEM images. The technique was used to confirm predictions of an earlier report of fatigue resistance.

Keywords:
fatigue, nitinol, compressive, SEM, stent, FEA (Finite Element Analysis)
